- Mouse used as encoder for odometry in a robotic car (with Arduino) This video shows how I managed to mechanically connect the motor of the Traxxas Emaxx to an old PS/2 ball-type (mechanical) mouse. The device is connected to an arduino to capture the data. The mouse encoder is modified so that it only counts two pulses per revolution because I prefer wider range than better precision. This is a cheap and easy way to build an odometry device for your robotic platform (if the motor does not provide those measures already). The sensor is part of the DreamBot project developed by Carlos Agell under the supervision of Professor Kane H. Kim and with the funding of Fundación Caja Madrid. This project is part of my MS thesis in the DREAM Lab of the EECS department at University of California, Irvine (USA). The autonomous vehicle will have a buch of other sensors.

Except for the features extraction process, the outlier removal and the motion estimation steps take less than 1mm on a normal laptop computer.

- Visual odometry in rough terrain Localization and mapping on autonomous robots typically requires a good pose estimate, which is hard to acquire if the vehicle is tracked.

- Stereo Visual Odometry with a hand-held camera Stereo Visual Odometry with a hand-held camera: Indoor Experiment.

- Robot Drives in a Circle Using Odometry Robot uses BASIC Stamp, simple 2-speed motor control relays and optical wheel encoders to drive a circular path and stop after completing a full circle. Path programmed is for the outside wheel to go twice as far as the inside wheel. The only reference is odometry feedback from the wheel encoders, which watch how far each wheel has turned and adjust the motor speeds to maintain the proper path. OD of circlular path is 5'-4", so the outside wheel traveled 16.75 feet. Demo here is on carpet, which is more problematic than a hard flat floor, yet the robot stops in the proper orientation and has drifted sideways only about 1/4 inch. Good accuracy & repeatability for such a simple system.

On the right, the current path estimation obtained with MLESAC + 5points algorithm. The odometry is estimated in 3D (six degrees of freedom) but for convenience in the video is projected in 2D.

- Visual Odometry using optical flow The source image is taken moving along a 1 meter tape. The optical flow needles are calculated between each frame and then the global optical flow vectors are found from by summing the components of the needles. There is some slight filtering on the minimum and maximum length of any needle. To find the distance the optical flow vectors are added in quadrature. The calibration is done based on a series of test frames from a variety of lighting conditions. Several other scenes give similar results. I should probably do some filtering on the global vectors. The routine requires about 30ms to process a frame on my laptop so runs at full frame rate. For more information see:

The robot is driven in a loop closing fashion and the results are compared against ground truth (trajectory with white nodes). Paper: WLD Lui and R.

- Lego NXT Car With Fuzzy Logic Using Odometry The point of fuzzy logic is to map an input space to an output space, and the primary mechanism for doing this is a list of "if-then" statements called rules. All rules are evaluated in parallel, and the order of the rules is unimportant. The rules themselves are useful because they refer to variables and the adjectives that describe those variables. Odometry helps to know where is the car so it can reach targets, in this case, the blue dots. Secuence of targets: ((-20, -20), (0, 0), (20, 20), (-20, -20), (20, 20), (0, 0), (-20, 20), (0, 0))

- Robot Odometry Test on Rugs Simple robot platform runs a small square pattern to test its dead reckoning ability. Ideally, the robot should end up exactly where it started, marked by two post-it notes on the floor. It encounters several real-world bumps along the way, which tend to knock a dead-reckoning robot off course. One wheel drives on and off of two different carpet runners, and the corner of the robot scrapes along the wall on its final turn. Yet it ends up within a half-inch of its starting position. The only sensors are wheel encoders, so the robot is driving blind, simply going forward x units then turning left y units, and repeating that 4 times to make a square. First test making turns on carpet, more to come.
